· JVASP-20924· K3AsS4

K3AsS4 is an inorganic ceramic compound containing potassium, arsenic, and sulfur. This is a specialized research material rather than a production commodity, belonging to the family of mixed-anion chalcogenides that are studied for optical, electronic, and solid-state chemistry applications. The compound is of primary interest to materials researchers investigating novel crystal structures, ion-conducting ceramics, and potentially photonic or thermoelectric properties in sulfide-based systems.
